Debugging

You know that feeling when you’re deep in a coding session, and your brain is juggling seventeen different things at once? You’re trying to fix a bug, but you also need to review some code, run tests, and maybe figure out why that one API endpoint is acting weird. It’s like being a one-person orchestra where everyone’s playing a different song. Well, Claude Code just handed us a solution that feels almost too obvious in hindsight: subagents. Think of them as specialized mini-Claudes that you can spin up for specific tasks, each with its own expertise and memory space. It’s like having a team of expert consultants you can call in whenever you need them, without them stepping on each other’s toes. ...

If you’ve ever tried to “read the mind” of a GPT‑4‑powered assistant, you know the feeling: you stare at a few lines of orchestration code and wonder why the thing just suggested buying a pineapple pizza for a corporate finance report. The answer isn’t in the handle_submit() you wrote; it’s in a sequence of invisible decisions that only a trace can reveal. That’s the premise of a recent TL;DR note I skimmed on a commuter train, and it got me thinking about how the whole discipline of software engineering is quietly being rewired. In the old world, the codebase was the bible. In the new world of AI agents, the trace—the step‑by‑step log of what the model actually did—has taken that role. ...
